    This evening Progress M1-4 led the ISS by about 4 minutes, rising in the west 
    and entering eclipse in the NW at about a 45 deg elevation.
    I acquired the Progress at 22:31 UTC about 5 deg below Altair at about a 4.5 
    mag.  About a minute later at 22:31:58 it was visible at 1x.  It's brightness 
    peaked at 22:32:06 at a -1 mag - clearly brighter than Vega.
    I acquired the ISS at 22:34:40 UTC, about 7 deg below Altair in the west.  It 
    was about -2.5 mag - brighter than I have ever seen it below 20 deg 
    elevation.  It dimmed to about a +0.5 by 22:35:30.   It seemed more brown-red 
    than the light blue color in previous passes.   I was expecting it to flare 
    after it passed beta-Cyg just as that Progress had done but it was steaty at 
    +0.5.   As it entered eclipse it turned a deep red.    
    There are visible passes tomorrow and Thursday here but the weather probably 
    will not cooperate.
